Recently (May 27, 2016) for ConfigMgr Current Branch (1602) is released, also known as KB3155482. It fixes multiple issues on both ConfigMgr and Microsoft Intune. It cannot be downloaded, but will be available in the ConfigMgr console instead.
Here's a list of issues that are fixed:
-Remote Control (1x)
-Site Systems (1x)
-Microsoft Intune and mobile device management (5x)
As you can see it fixes mostly Intune (MDM) parts. When not using Intune, just wait for build 1606 coming soon.
This hotfix is available for installation in the Updates and Servicing node of the ConfigMgr console. If the service connection point is in offline mode, you have to re-import the update so that it is listed in the ConfigMgr console.

Hopefully the ConfigMgr certificate issue is solved now too!
